Abstract
This is the DEM data for the watershed boundary for French Broad River near Newport. This resource includes one TIFF image presenting the projected DEM data of watershed boundary for French Broad River Near Newport and one txt file containing the Python code used to download and process the original DEM data. The input data is http://www.hydroshare.org/resource/860155baa06d46f1a0c3e0bf48e9b348 , provided by Dr. Venkatesh Merwade.
The code has some minor problems with the last line of Cell 7. Currently it can download, merge and project the DEM data and save them as TIFF file. We're still working on clipping the TIFF image so it can be complete. To run the code, read the instructions in readme.txt.

The txt file "DEN_NED.txt" is a Python program that can automatically download and process the DEM data according to the shapefile input. However, the code has some minor problems with the last line of Cell 7. Currently it can download, merge and project the DEM data and save them as TIFF file. We're still working on clipping the TIFF image so it can be saved into the output folder. To run this program, Jupyter Notebook with anaconda 5.1 on MyGeoHub is needed. How to use: 1. Create an input folder and an output folder under your Jupyter Notebook working directory. Upload the Shapefile into your input folder. 2. Change the filename extension of ".txt" to ".ipynb" and open it. 3. In the cell titled "USER INPUTS",provide the full path of your input and output folders cerated in Step 1 at the requisite lines. Also, provide the name of the shapefile you prepared. 4. Run Cell 1 to Cell 7 in order. DO NOT run the last one or the work folder will be deleted. 5. Open the work folder in your input folder. The projected DEM image is saved as proj_rast.tif.
